 ## Future Extensions
 
 I have now been running capacitive ground moisture level sensors in a couple of my plants for around a year, logging the data using my [ESP-Env project](https://git.xythobuz.de/thomas/esp-env) to an [InfluxDB](https://www.influxdata.com/) instance running on my NAS, with a [Grafana](https://grafana.com/) UI running on there as well.
